This issue occurs when the Unity server is not able to communicate with
Mailstore (Exchange/domino) due to various reasons. Sometimes the permissions
applied to the mailbox store can cause this issue. In order to resolve this
issue, run the Permission wizard and set the permissions again on the mailbox
store. Refer to
Granting
Permissions with the Cisco Unity Permissions Wizard for more information
on permissions set by the wizard.

If the subscribers still cannot access the Mailstore after the
Permission wizard is run, perform the following procedure to resolve this
issue.

Note: You need to go to Start > Settings > Control Panel >
Add/Remove programs and remove the Cisco Unity Message Store
Configuration Wizard from the Cisco Unity server before you proceed with these
steps:

Run C:\commserver\configurationsetup\setup.exe
/sync to reconnect Cisco Unity to its current Exchange.
